TPO Waterproofing Membrane Reinforced by Polyester Fabric for roof

length : 20m（Above quantities are indicative only. We can produce it according to your demands）.

Introduction

TPO, the abbreviation of
thermoplastic polyolefin, is made with the dynamically vulcanized EPDM
thermoplastic EPDM, the main ingredients of the composition of PP and EPDM. TPO
mainly contains carbon atoms and hydrogen atoms and does not contain any
plasticizers and chlorine elements. It is a beautiful, long-lived
environment-friendly product.

ü No
plasticizer. They have been tested as having excellent resistance to thermal
aging and ultraviolet, durable and exposed.

ü Hot-air
welding. The peel strength of joint is high.

ü Fast
welding speed.

ü Environment
friendly, 100% recycled, without chlorine.

ü Durable
hot welding performance and easy to repair.

ü Smooth
surface, no fading and pollution.

Applications

Widely used in the roofing and
underground constructions of industrial and civil buildings. For different
bases and constructions, PVC membranes are installed mechanically-attached,
fully-adhered or ballasted.

Packing

Rolled with hard materials and packed
with plastic bags or woven bags.

Storage

TPO material should be stored in
well-ventilated place and avoid being exposed to the sun or rain. The
temperature in stored places can not be higher than 45° C. It only can be put
horizontally in five-level. It has to be avoided acid, alkali, oil and organic solvents.
The shelf life is 1 year.

Transport

TPO material should avoid inclination
or lateral drift during transportation. When necessary, it covered with felted
fabric.

Application
Methods

For Fully Adhered Roofing System

Before application, spread TPO
membranes on substrate in advance. Install TPO membranes on the substrate
without distortions according to the flange. The overlapping width should be
more than 50 mm. Hot-air welding is adopted for laps with 40 mm welding width.
Professional adhesives need to be used on both underside and substrate surfaces
to adhere and maintain.

For Ballasted Roofing System

Before application, spread TPO
membranes on substrate in advance. Install TPO membranes on the substrate
without distortions according to the flange. The overlapping width should be
more than 50 mm. Hot-air welding is adopted for laps with 40 mm welding width.

Attentions

Ø
TPO membranes reflect
heat and light. Be sure to wear protective clothing (long-sleeved shirt,
long-barreled trousers), and wear a filter to protect the skin and eyes from
UV-induced damage.

Ø
Security
measures for roof perimeter are necessary during application. Sheet
surface is slippery when wet and therefore, take care to avoid slide.

Ø
Sealants and adhesives
are flammable containing solvents. They will be dangerous when exposed to heat,
even have the possibility to catch fire and explode.

Ø
Sealants, adhesives,
cleaners should be avoided contacting with skin and eyes.
